Intravitreal Injections (IVT), Lens Opacification
Conditions
Keywords
Cataract, objective scatter index (OSI), average lens density (ALD)
Brief summary
The main hypothesis is the opacification of the lens would be increase by the IVT. The opacification of the lens can be objectived by : * the objective scatter index (OSI) on the OQAS device * the average lens density (ALD) on the IOLMaster device. Eligible patients will be followed at least 12 months after in intravitreal injection and the opacification of their lens is regularly controlled with OSI and ALD. The objective is to study the dynamics of lens opacification in IVT-treated eyes evaluated by OSI for at least 1 year.
Interventions
DIAGNOSTIC_TESTMeasurement of lens opacification
Measurement of OSI and ALD at inclusion and during post-IVT follow-up visits to M3, M6, and M12, +/- M18, +/- M24 and +/- M30.
